Add and update Big 10 logos and content
Added logos and content for University of Maryland and Rutgers University. Updated all logos to SVGs with PNG fallbacks. Will need to improve layout in a subsequent update.
On Saturday, July 27 from 8:00 AM to 9:00 AM, we will be performing an upgrade of the GitLab system. During that time, GitLab and git services on git.unl.edu may be unavailable.
